I have copied the contents of the 4nt6a folder from my Windows 98 system, to my Windows Vista Business 32-bit system.

4nt6a seems to be working okay (I ran the examples.btm file).

When I did a ver /r, I noticed that it did not have my registration info, so I ran the br4nt.exe program.

I still have the blue JP CD Suite Brand ID Card that came with my JP-CD Suite Release 3.

I could not, however, get the br4nt.exe program to brand my copy of 4nt.exe, which produced the following;

Thus, a ver /r produces

It does not really matter if I can brand or not, as I don't intend to use 4nt6a on my Windows Vista Business 32-bit system, but I just wanted to see if it could be done.

I still use Microsoft Visual FoxPro 5.0 on both my Windows Vista Business 32-bit system, and my Windows 7 Professional 64-bit system, and it still does what I require it to do. Ditto for Microsoft Word 97, Microsoft Excel 97, and Microsoft Access 97, and Microsoft Visual Basic 5.0.

No reason to upgrade to the latest and greatest, if what you have already does what you need.

Just a guess, but are you running BR4NT while 4NT is actually running? I bet it cannot modify the 4NT executable while it is running. (Assuming that's what BR4NT is doing... modifying 4NT.exe... which I believe was the case back then....)
